Hello all,

I am new to Gatling and Scala,

I want to create two simple scenarios using Gatling. I have installed scala plugin in eclipse. Installed Gatling. I am able to run basic simulations present in Gatling’s zip folder from command prompt. I tried to write below script FacebookLogin.scala. In cmd it gives error- missing semicolon before value param.

Please let me know best resources to learn Gatling as well.

import io.gatling.core.Predef.\_  
import io.gatling.http.Predef.\_  
import scala.concurrent.duration.\_

class FacebookLogin extends Simulation {

val httpConf = http  
.baseURL(“[https://www.facebook.com](https://www.facebook.com)”)  
.acceptHeader(“text/html,application/xhtml+xml,application/xml;q=0.9,_/_;q=0.8”)  
.doNotTrackHeader(“1”)  
.acceptLanguageHeader(“en-US,en;q=0.5”)  
.acceptEncodingHeader(“gzip, deflate”)  
.userAgentHeader(“Mozilla/5.0 (Macintosh; Intel Mac OS X 10.8; rv:16.0) Gecko/20100101 Firefox/16.0”)

val scn = scenario(“LoginToFacebook”)  
.exec(http(“Login page”)  
.get("/"))

.exec(http(“Login”).post("/login")  
.param(“username”, “user”)  
.param(“password”,“password”)  
.check(css(“username”).is(“user”))

setUp(scn.inject(atOnceUsers(1)).protocols(httpConf))  
}

You probably used an old documentation or outdated samples found on the Internet.  
Param has been renamed into formParam. Check migration guides.
